MED MODIFIED A+ CRANKSHAFT

Due to popular demand, MED re-worked crankshafts are back, for 1275 engines with A-plus (1.750") big ends. These are based on the latest design of Rover Mini crankshaft, modified for high performance road and trackday engines.

Specifications

• Std/std journal sizes

• Heat treated journals

• Cross-drilled mains

• Wedged to improve counterbalance and reduce weight

• Balanced dynamically to within 1g

The crankshafts are CNC-machined to improve counterbalance and also reduce overall weight. More specifically, we've re-profiled the web around the big end journal area, where this has the most effect.

Once machined and balanced, we have a ni-temper treatment applied before a specialist polish and quench technique to improve journal durability.  

Modified using decades of A-Series engine experience.

Available separately or as a complete kit with ACL main bearings, big end bearings and thrust washers to suit.
